1 Claim.

This invention relates to ladders and has for its object to provide a combination step-ladder and straight away ladder.

Another object of the invention is to provide a ladder for reaching high position and which may be quickly converted into a step-ladder.

A further object of the invention is to provide a ladder comprising a plurality of members so arranged that all may be locked together by very simple means.

Other features and advantages will become more readily apparent from the following description and the accompanying illustrative drawings in which? Figure 1 is a side elevation of my improved ladder shown as a straight ladder,

Figure 2 is a similar view of the same shown as a step ladder,

Figure 3 is a front elevational view of Figure 1,

Figure 4 is an elevational view of the ladder shown in collapsed position,

Figure 5 is a detail view of a combined shelf and brace, and

Figure 6 is a detail perspective view of the shelf.

In the accompanying drawings as above enumerated and in the following specification, like characters of reference indicate like parts throughout and in which l0, indicates my improved household ladder which consists of ladder sections II and I2, the side bars l3 and ll,

of section I I, being flared apart at their foot ends l5 and I6, and the free ends i1 and [8. of the side bars i3 and 20, being similarly flared apart.

The upper ends 2| and 22, of members l3 and I4, are parallel and have pivotally connected thereto by bolts 23 and 24, at points about twelve to eighteen inches below the extreme terminals 25 and 26, thereof the extreme upper terminals 21 and 28, of the members is and 20, which are also parallel at this point and which at snugly between said parts 2| and 22, when the member I2 is raised to aligned position with member II, to

form a straight ladder, designated as a whole by character '29, The upper portions 30 and 3|, of said members i9 and 20, are held braced to member H, by means of the uppermost step 32, thereof, whereby the members II and I2, when aligned and the ends I! and I8, leaned against a wall or other support are held rigidly connected.-

Pivotally connected to members 19 and 20, are arms 32 and 33, to which is secured a shelf 34, the outer edge 35, of which is provided with spaced apart cut-outs 36 and 31, into which are screwed hooks 38 and 39, adapted for engagement with projecting screw-eyes 40, in the extending ends 8i and B2, of step 43, when the device is used as a step-ladder as indicated in Figure 2 of the drawings. A button 44, is pivotally connected at 45, to the upper part 22, of the member H, to further secure the members It and 20, in place when the latter member is in up position.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and rearrangement of details and parts such as come within the purview oi. the invention claimed may be resorted to, in actual practice, if desired. I

Having now described my invention that which I claim as new and desire to procure by Letters Patent is:

A ladder formedof two pivotally connected sections, one being an extension section, a shelf pivotally connected to the latter section and having recesses in its free transverse edge, hooks located in the recesses, eyes on a step 0! the other section adapted to be engaged by the hooks, a button onthe latter section adapted to engage the extension section when in raised position.
